But not enough drama | TOO MUCH SUN by Nicky Silver at Vineyard Theatre does not amount to much

Not a single thing makes sense here. Except desire to see Linda Lavin on stage. Ahistorical summer comedy puff ball that could have been written 25 years ago. Every cliche in book, from married (to woman) guy discovers he’s gay, to random suicide, to surprise pregnancy via previously unknown affair. Huh?
